실험 절차

4-Amino-3-fluorophenol (0.254 g; 2.0 mmol) was dissolved in 10 ml of dry pyridine under nitrogen and cooled to 0° C. Methanesulfonyl chloride (0.17 ml; 2.1 mmol) was added dropwise and stirred for three days at room temperature. The reaction was evaporated, 25 ml of toluene added and evaporated again. Toluene evaporation was repeated. Residue was dissolved in 25 ml of EtOAc, washed with 20 ml of water and evaporated to dryness to give red-brown solid N-(2-fluoro-4-hydroxyphenyl)methanesulfonamide. 1H NMR (400 MHz, DMSO-d6): 2.93 (3H, s), 6.56-6.66 (2H, m), 7.14 (1H, t, J=9.0 Hz), 9.17 (1H, s), 9.98 (1H, s).
